Everyone knows that high energy radiation is dangerous. It can
cause mutations, cancer, atherosclerosis, cross-linking (Loss of
tissue elasticity), brain damage, immune system damage etc. This
could also be a list of damage caused by aging and our
environment. The similarity is not coincidental. Nearly all
high-energy radiation causes its damage by creating dangerous,
highly reactive chemicals called free radicals.

Unfortunately we cannot escape free radical damage by avoiding
radiation, because chemical reactions in our bodies create free
radicals too. Some of these are normal and necessary, but others
are pathologic and cause damage. Ordinary air on a sunny day
contains about 1000 million hydroxyl free radicals (the most
dangerous type of free radical) per litre of air.

Thats the bad news, the good news is that certain nutrients are
very effective in destroying pathologic free radicals. By
controlling free radicals you are protecting yourself from both
internal and external radiation, and ageing. Since your life
depends on the very careful control of the chemical reactions
within you, free radicals can be deadly.
